A screen multiplexer utility which lets you run multiple interactive terminal sessions (and curses programs) through a single terminal connection (on one virtual console, one terminal, through one modem link, telnet session or xterm). Screen can detach processes from one terminal and attach them to another. "Auto-detach" lets you continue working after being disconnected and reconnected. It supports keyboard driven cut and paste from any text and/or curses application (like Lynx) to any other (like xemacs). Screen comes with many Linux distributions and is available (free) on many other Unixplatforms. (2005-07-29)
